Thanks so much, Don. Do you know if each room usually has the same steward throughout the cruise? That will make a difference too,I am sure. Sorry, to be a cruise dummy but what do you mean by the 2nd group?You will have the same steward for the entire cruise. What I meant was that have the people believe that giving the steward a tip when they board gets them better service; half the people believe that you get good service regardless. I belong to the "do not tip at the start of the cruise" group.
